Polymer in solution measurement

[u/_sixty_three_]

I'm looking for types of analysis that can determine the % of polymer in a solvent solution. Anyone work in polymer industry that can help? Preferably continuous measurement but if samples need to be taken for lab analysis so be it

[u/ttume54]

It’s fairly simple. For a continuous process, you measure the rate of the vaporized solvent and the flow rate of the polymer going out. Use that to find the percentage.

[u/_sixty_three_ → u/ttume54]

The solution is in direct contact with steam so can't measure the amount of solvent vapourized so easily. The aim is to have a good measure of the % polymer to better control and adjust the steam input to optimise the process.
